 Status of TR1 features in GCC

<p>
This table is based on the table of contents of ISO/IEC DTR 19768
Doc No: N1836=05-0096 Date: 2005-06-24
Draft Technical Report on C++ Library Extensions

<p>
In this implementation the header names are prefixed by
<code>tr1/</code>, for instance <code>&lt;tr1/functional&gt;</code>,
<code>&lt;tr1/memory&gt;</code>, and so on.
</p>

<p>
This page describes the TR1 support in mainline GCC CVS, not in any particular
release.
